Abstract: A sleeve assembly includes a sleeve having a hexagonal hole and a rectangular hole in two ends thereof and a positioning hole is defined through a wall of the sleeve and communicates with the hexagonal hole. A control member is rotatably mounted to the sleeve and a bead is located between the control member and the sleeve. The bead is movably engaged with the positioning hole. The control member includes multiple first reception portions and second reception portions defined in an inner periphery thereof. The bead is completely received in one of the first reception portions or partially received in one of the second reception portions by rotating the control member. When the bead is completely received in one of the first reception portions, the object in the sleeve drops off from the sleeve.

Abstract: A socket assembly includes a socket having a mounting hole which includes a plurality of insides and yield recesses located alternatively between the insides. A control member is rotatably mounted to the socket and has a through hole, a plurality of stops extend inward from an inner periphery of the through hole. The stops are deformable when being applied with a force along the axis of the through hole. A polygonal object can be forced into the mounting hole by squeezing and bending the stops. After the object is loosened and received in the socket, the stops support the nut from dropping from the mounting hole. When the control member is rotated to off align the stops from the path that the corners of the polygonal object may drop, the object is easily take out from the socket.

A control member is rotatably mounted to the socket and has a through hole, a plurality of stops extend inward from an inner periphery of the through hole. A polygonal object is engaged with the mounting hole of the socket and the stops of the control member are located on the path along which the polygonal object may drop from the socket. After the object is loosened and received in the socket, the control member is rotated an angle to remove the stops such that the path that the polygonal object may drop is clear and the object is easily take out from the socket.
